In the past I have always fed 3 times a day, my calf last year was fed three times aday, full bottles. This year, Brat is getting 4 bottles aday, she's fed on the same schedule as my goats, she gets 3/4 a bottle each feeding, she gets an egg in her morning bottle, she is technically getting the same amount as last years calf, just spread into 4 instead of 3 feedings, and she's growing like a weed! In my experience calves always act hungry! I think she'd eat herself to death if I let her. Are you offering starter feed? If not I would, right now after Brat's bottle I give her alittle feed to suck on, that seems to keep her attention while I finish up w/ the goats. She'll be 3 weeks old tomarrow and I've been feeding her this way since she was 2 days old.
So yes, if these were my calves I'd feed them 3 bottles aday (altough I wouldn't do it all at once if they are use to 2, I'd go slowly so you don't make them sick). I think I only fed my very first bottle calves (looong time ago, but I still have the steer and he's big and healthy) 2 bottles a day, and I'd give them a 1 pint bottle of water about 30 min after their bottles (this is what the seller had told me to do), I could be mistaken it was a long time ago, but whatever I did, those two grew very well.
If you post pics of them from above I bet some of the experienced bottle raisers may be able to tell you if they look thin! Post one before a bottle and one after!
As for Avery maybe someone w/ more experience will chime in, does he have a temp?
